An organization wants to collect an account number from a customer via IVR prompting. Then, using a keystroke macro, they want to pop the account number into the account number field in the agent's CRM desktop application. The keystroke macro will also initiate the CRM desktop application, executing a database lookup from the CRM Database server to retrieve the customer record. Assuming the organization wants the lowest cost solution, 
what product does this organization need for this capability?（）
